Working Principle of Solar Collector
Combined various collectors with water storage tank as a complete projects.
Water in solar vacuum tube for heat transferring, by circulation pump and relative system to take the heat to water tank.
Non-pressure Vacuum Tube Solar Thermal Collector consists of all-glass vacuum tube,
non-pressurized manifold and support bracket, working principle is the same as integrated non-pressurized system, taking advantage of the natural circulation due to larger proportion of hot water to cold water.
Series or/and parallel connection arrays of solar collector is usually adopted for large-scale hot water heating projects.
